### SSRF PHP funksies

Sommige funksies soos **file\_get\_contents(), fopen(), file(), md5\_file()** aanvaar URL's as insette wat hulle sal volg en maak **moontlike SSRF-gebreke** moontlik as die gebruiker die data kan beheer:
```php
file_get_contents("http://127.0.0.1:8081");
fopen("http://127.0.0.1:8081", "r");
file("http://127.0.0.1:8081");
md5_file("http://127.0.0.1:8081");
```
### CRLF

Verder, in sommige gevalle kan dit selfs moontlik wees om arbitrêre koppe via CRLF "kwesbaarhede" in die vorige funksies te stuur:
```php
# The following will create a header called from with value Hi and
# an extra header "Injected: I HAVE IT"
ini_set("from", "Hi\r\nInjected: I HAVE IT");
file_get_contents("http://127.0.0.1:8081");

GET / HTTP/1.1
From: Hi
Injected: I HAVE IT
Host: 127.0.0.1:8081
Connection: close

# Any of the previously mentioned functions will send those headers
```
{% hint style="warning" %}
Vir meer inligting oor daardie CRLF-fout, kyk na hierdie fout [https://bugs.php.net/bug.php?id=81680\&edit=1](https://bugs.php.net/bug.php?id=81680\&edit=1)
{% endhint %}

Merk op dat hierdie funksie moontlik ander metodes het om arbitrêre koppe in versoeke in te stel, soos:
```php
$url = "";

$options = array(
'http'=>array(
'method'=>"GET",
'header'=>"Accept-language: en\r\n" .
"Cookie: foo=bar\r\n" .  // check function.stream-context-create on php.net
"User-Agent: Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.102011-10-16 20:23:10\r\n" // i.e. An iPad
)
);

$context = stream_context_create($options);
$file = file_get_contents($url, false, $context);
```
